Overnight, police filed new charges against 35-year-old Granville Ritchie, including four counts of having sex with a minor. Police say those charges are not directly related to 9-year-old Felecia, whose body was found near the Courtney Campbell bridge this past weekend.

Instead, they're part of a disturbing revelation made in the course the investigation into Felecia's death.

At a news conference late Wednesday, Temple Terrace Police Chief Ken Albano said with Ritchie now behind bars, anyone who'd been hesitating to come forward with information could now do so without fear of retribution.

"Help us bring the murderer of this little girl to justice," said Chief Albano.

And now it appears another young girl has done just that.

Detectives say during their investigation, a girl who they thought may have been a witness in Felecia's case disclosed to them that Ritchie had sexual contact with her four times in the past month.

"I live right here – and he lived right there!" said Paula Fontanec, pointing toward Ritchie's apartment.
